Fix #1135: added RTP padding checks and RTP payload length adjustment according to padding length.
Payload padding in outgoing RTP investigation results:
- the RTP does not specify RTP payload alignment.
- most codecs also do not specify RTP payload alignment, usually only octet-alignment is specified and this seems to be done.
- SRTP, RFC3711 states:
- None of the pre-defined SRTP encryption transforms uses any padding; for these, the RTP and SRTP payload sizes match exactly.
- Message authentication codes define their own padding.
- Encryption transforms that use padding are vulnerable to subtle attacks, especially when message authentication is not used.
So, currently payload padding in outgoing RTP is not necessary.
